Why You’ll Love This Recipe

PB Banana Power Shake is built around classic peanut butter and banana flavor. Peanut butter makes it rich, banana adds natural sweetness, oats give it body, and vanilla protein adds extra staying power. Oat milk helps everything blend creamy and keeps the flavor soft. It is a good option when you want a thicker protein-focused breakfast or post-workout shake that feels like a real meal.

Make-Ahead Tips

Measure the rolled oats and protein powder into separate dry containers the night before. Peel and freeze the banana if you want a colder, thicker shake. Keep the oat milk and peanut butter separate until blending time. When ready to blend, pour the oat milk into the blender, add the oats, and let them soak for 5 minutes before adding the remaining ingredients. Do not freeze the dry oats and protein powder inside the same bag as damp fruit because the powder may clump. A blended shake can be refrigerated in a sealed jar for up to 24 hours, but it will thicken as the oats absorb liquid. Shake or re-blend it with a small splash of oat milk before drinking.

Texture and Flavor Notes

This shake should be thick, creamy, and smooth. The oats make it more filling, but they need enough blending time so the texture does not turn gritty. Letting the oats sit in oat milk for 5 minutes before blending helps them soften. Peanut butter and banana make the shake creamy, while vanilla protein adds sweetness and body. Blend longer than you would for a fruit-only smoothie.

Instructions

  1. 1Gather the peanut butter, banana, rolled oats, vanilla protein powder, and oat milk before you start.
  2. 2Pour the oat milk into the blender first so the blades have liquid to work with.
  3. 3Add the rolled oats to the oat milk and let them sit for 5 minutes for a smoother blend.
  4. 4Peel the banana and break it into a few pieces.
  5. 5Add the banana and peanut butter to the blender.
  6. 6Add the vanilla protein powder near the middle of the blender so it blends into the oats and peanut butter instead of sticking to the lid.
  7. 7Secure the lid and blend on low for about 10 seconds to start breaking everything down.
  8. 8Increase to high and blend for 45 to 75 seconds, or until the shake looks thick and creamy with no dry rolled oat pieces, banana chunks, peanut butter streaks, or protein clumps left.
  9. 9Stop the blender and taste a small spoonful. Add a splash more oat milk if it feels too thick.
  10. 10Pour into a glass and drink right away while it is smooth and creamy.

Tips and Tricks

  1. 1

    Soak the oats in oat milk for 5 minutes before blending so the shake is not gritty.

  2. 2

    Use frozen banana for a thicker milkshake-style texture.

  3. 3

    Add the protein near the middle of the blender so it does not stick to the lid.

  4. 4

    Use sunflower seed butter for a nut-free version.

  5. 5

    Blend longer than a fruit-only smoothie so the oats fully break down.
